In this letter, we consider static black hole in f(R) gravity.We take advantage from corrected entropy and temperature and investigate such black hole. Finally, we study the $ P - V $ critically and phase transition of corrected black hole with respect to entropy and temperature. Here also, we obtain the heat capacity for the static black hole in $ f(R) $ gravity. This calculation help us...

We consider the classical Hamiltonian of interior Schwarzschild black hole in Ashtekar-Barbero connection formalism. Then, inspired by generalized uncertainty principle models, we deform canonical algebra and derive effective dynamics model under this modification. show that such a deformation leads to resolution singularity minimum nonzero radius for infalling 2-spheres, provided parameters ar...

The hole drilling method is one of the most used semi-destructive techniques for residual stress analysis of mechanical parts. In the presence of non-uniform residual stresses, the stress field can be determined from the measured relaxed strains using several methods, but the most used is the so called integral method. This method is characterized by some simplifications that lead to approximat...

The present work aims at reducing the friction of rubber soles sliding on ceramic floorings. Fitting bored cylindrical protrusions with different diameters on rubber soles was proposed. Experiments were carried out to evaluate the performance of the proposed protrusions in increasing friction coefficient at dry and contaminated floorings. It was found that, at dry sliding, friction coefficient ...

To achieve geometric reconstruction from 3D datasets two complementary approaches have been widely used. On one hand the deformable model framework locally applies forces to t the data. On the other hand, the non-rigid registration framework computes a global transformation minimizing the distance between a template and the data. We rst show that applying a global transformation on a surface te...

many experimental studies have been conducted on development of the scour hole as a result of vertical jet impaction. research has shown that aeration of the nappe flow in the model is much weaker than that in the prototype. therefore, the influence of aeration on scour holes needs further study. experimental investigation of the effects of air entrainment and tail water depth on the scour hole...

The increase in the sensitivity of gravitational wave interferometers will bring additional detections binary black hole and double neutron star mergers. It also very likely add many merger events - binaries. Distinguishing mixed binaries from holes mergers for high mass ratios could be challenging because this situation coalesces with without experiencing significant disruption. To investigate...

Abstract In this study, the gravitational decoupling approach via extended geometric deformation is utilized to generate analytical black hole solutions owing its simplicity and effectiveness. Considering external fields surrounding Schwarzschild AdS holes, we derive hairy in asymptotic spacetime, satisfying strong dominant energy conditions. Moreover, find that if spacetime a fluid system, und...
